My battery died after 2 wks at the airport parking lot and had to get my car jump started. Since then, my amps aren't turning on, going into protect mode. I checked connections with my multimeter and found that I am getting a voltage of ~10V after my inline fuse right off the battery, 14V before the fuse. Simple question, am I correct in assuming that this means the fuse is bad and needs replacement?
Hmm, doubtful the fuse itself is a problem. Fuses usually work, or they don't.
There might be something else wrong near the fuse like corrosion or a poor connection. I suspect there is something you haven't found yet.
Hmm. I mean I guess the fuse holder isn't completely sealed, and I do live in the Midwest. I just don't get why the problems would present only after the jump start. With the voltage drop after the fuse, there shouldn't be any reason to check stuff downstream correct?Quote:

You could also check the continuity and/or resistance with a DMM from one end to the other (not installed) and see what you get.
It's an ANL fuse. I've got fuses on order. Will check continuity.Quote:
